Overview
IEC 63145-10:2023 - Eyewear display: Part 10: Specifications defines the optical and performance specifications and requirements for eyewear displays that use virtual image optics. It applies to both virtual reality (VR-type, non-see-through) and augmented reality (AR-type, see-through) eyewear displays. Prescription lenses are explicitly out of scope. The standard organizes specification tables, measurement conditions and calculation rules and refers to several measurement-method parts in the IEC 63145 series for test procedures.
Key topics and technical requirements
IEC 63145-10 structures practical, testable specifications around measurable optical characteristics:
-
Luminance
- Maximum/minimum centre luminance, nine‑point and average luminance, and luminance uniformity for full‑screen white.
- Methods and conditions for luminance measurement (referenced to IEC 63145-20-10 and related parts).
-
Contrast and image quality
- Centre contrast ratio and nine‑point contrast ratios with defined measurement conditions.
-
Chromaticity and color gamut
- White point, RGB chromaticity (u′, v′), chromaticity gamut percentage and chromaticity uniformity.
-
Transmittance (AR-type)
- Spectral directional transmittance classification and measurement conditions for see‑through AR optics; tables link transmittance classes to typical ambient illuminance/use cases.
-
Field of view (FOV) and eye‑box
- Diagonal FOV measurement methods and eye‑box width/height specification and measurement conditions.
-
Resolution and pixel count
- Number of electrically addressable pixels (H × V) and related notation.
-
Video see‑through and luminance ratio
- Specific tables and requirements that address video see‑through eyewear displays, including luminance ratio of virtual image relative to background and guidance for automatic/manual luminance adjustments.
-
Ancillary topics
- Common measurement/calculation conditions, stray light considerations (informative annex), and example scene illuminances for indoor/outdoor use.
Practical applications and who uses it
IEC 63145-10 is intended for stakeholders involved in the design, testing, procurement and regulation of AR/VR eyewear:
- Display and optical engineers validating product performance
- Test laboratories and certification bodies performing conformance testing
- Product managers and procurement teams defining technical requirements
- R&D teams benchmarking prototypes and optimizing ergonomics and visibility
- Regulators and standards bodies assessing safety and interoperability
Use cases include product specification, acceptance testing, comparative benchmarking, and documentation for compliance.
